Abstract :

RFID door access system is provides the best way to secured door lock. The RFID reader is placed on the outside of the door and is separate from the main controller circuit, which is on the inside so that no one can circumvent the security by breaking open the Reader and trying to short circuit the reader. The controller receives serial data from the Reader and controls the Door lock or unlock.


RFID card reader reads the card shown and sends uart data to the micro-controller 8051. The 8051 micro-controller read this data and match it with saved programmed card data. After matching it, micro-controller sends the signal to L293D, H bridge motor driver IC, to control the motor for door lock and unlock. There is also a 16×2 character LCD is connected to micro-controller for display information. The LCD display the information that card is matched or not matched and if it matched then it also display that “door is unlock”. In case it is not matched the LCD display that “card error”. There is a Push button connected to micro-controller for door lock.

Hi friends
First of all, we thank you because you may have used our website below.
We are happy to tell you that Techsodes Corporation has created the microcontroller open source code editor named as MikroStudio IDE first time in India. This software is a power full tool for code development of microcontrollers like 8031, 8032, 8051, 8052, Mcs51, AVR, PIC, STM8, Z80, EZ80, Z180, padauk, rabbit and gameBoy etc. It is absolutely free and is also better than other programmable software or IDE (Integrated Development Environment) because they can programmed only few microcontrollers. MikroStudio IDE has been support 3000+ microcontroller without installation other cores or plugin. MikroStudio IDE used sdcc, avr-gcc and gputils compilers. MikroStudio IDE has also provides you an open source hardware and software community where you can discuss your problems with us and that problem will be solved by the community.
